Berge Bulk’s Berge Neblina has set sail following the installation of Anemoi’s energy saving Rotor Sails. The 388,000-DWT Valemax ore carrier, left for Brazil following the installation of the four 5-x35-metre Rotor Sails.

The installation, which was completed quayside, took place at Yiu Lian Dockyards (Shekou) Ltd in China. The selected Rotor Sails have been installed on Anemoi’s bespoke folding deployment system, whereby the sails can be folded from the vertical to mitigate impact on air draught and cargo handling operations when in port.
‘Leveraging the latest in wind technology to reduce our fleet’s emissions is an important part of Berge Bulk’s “Maritime Marshall Plan” for decarbonisation,’ says Paolo Tonon, technical director of Berge Bulk. ‘We are optimistic that these Rotor Sails can deliver up to eight per cent carbon reduction.

Rotor Sails
Rotor Sails, also referred to as “Flettner Rotors”, are comprised of vertical cylinders which, when driven to rotate, harness the renewable power of the wind to propel ships. These highly efficient mechanical sails capitalise on the aerodynamic phenomenon known as the Magnus Effect to provide additional thrust to vessels.

By leveraging wind energy, Berge Neblina will see increased efficiency by reducing the load on the main engine while maintaining speed, therefore substantially reducing fuel consumption and resulting in less greenhouse gas emissions.
Rotor Sails are a compact technology, which offer a large thrust force to propel ships, helping them comply with pivotal international emission reduction benchmarks such as the Carbon Intensity Indicator (CII) and EEDI/EEXI.
